Editor’s Note: The following is an excerpt from an article in Automotive News detailing operations at Ohio GMC truck and RV dealer Holman Motors. Owner Greg Holman has found the combination profitable, as he says RVs are “a giant accessory for a truck buyer.” To read the entire piece click here.

Drivers passing by Greg Holman’s GMC dealership outside Cincinnati likely can’t help but notice the four-story mountain of boulders strewn with more than a dozen pickups and SUVs.

Holman believes the structure — built over three years by hauling thousands of limestone boulders from a local quarry — is the biggest outdoor truck display anywhere.

But as big as the boulder display is, it’s only a small aspect of Holman Motors.

The dozens of GMC trucks at the dealership are among a sea of hundreds of hulking travel trailers, or towable campers, on the 32-acre lot.

Last year, Holman sold 1,100 new travel trailers from more than 20 manufacturers, which makes him the No. 2 retailer of towable RVs nationally, according to Statistical Surveys Inc. of Grand Rapids, Mich.

He holds his own with GMC truck sales, too: Last year, Holman, in Batavia, Ohio, 20 miles east of Cincinnati, sold 523 new GMCs, good for No. 1 in Ohio, General Motors confirms.

What some might perceive as a logistical headache, Holman sees as a competitive edge. Holman Motors has sold GMCs and RVs from the same lot for 30 years. Salespeople sell trucks and campers — ideally to the same customer.

Holman, 58, views an RV as a giant accessory for a truck buyer. In many cases, though, the truck becomes the accessory. An RV buyer might be convinced that, by stepping up to a Sierra heavy-duty pickup, he’ll be able to buy more camper.

“The first question out of a prospective camper owner’s mouth is usually: ‘Is my truck adequate to pull the camper I want to buy?'” Holman says. “Well, we’re the experts. We know exactly what their truck is capable of, and can steer them to the right truck to match the right camper.”
